Pre-order Guitar Hero: Van Halen while you wait for Activision to announce it

Several listings at GameStop's site earlier today revealed Guitar Hero: Van Halen. The listings have since been pulled, but we managed to take a screen cap for you, which you can see past the break. It's a game that has been rumored for a little while now, and would be Activision's next logical step following Guitar Hero: Aerosmithand Guitar Hero: Metallica. Each listing at GameStop's site points to an August 4 release for the title on PS2, PS3, Xbox 360, and Wii. So what are you waiting for, Activision? Just announce the thing already!
